I suspect he is using an insert here. I used to have larger versions of the images, but seem to have mislaid them at some point and Brian's site no longer appears to link to them.
Can you elaborate on what you mean here? It seems to be about pumping out water, but the context before your post is guns?
Ooooo, you want mostly sealed barbettes to keep the water out. Not really an issue unless you've got low freeboard.
FYI, the max pressure rating you see is generally the max working pressure, not the pressure it will fail at. Working pressure has a built in safety margin based on ASME code or similar. For example 1/8" Clippard tubing has a pressure rating of 105 psi, but a burst pressure of about 425 psi. That's why we can routinely use the tubing at 150psi without any problems.
With duals in the D turret angled to 15 degrees, it looks like I'm impacting at 13" out with a 4 degree down angle. Will this be lethal or will I be skipping bb's and foregoing range that straight back sterns would give?
If I remember right you skip at about 7-8 degrees or less of down angle. It might be better to use that turret for a side mount and use the lower one for your stern guns.
Yep, you'll be skipping with less than the 7-8 degree down angle. And with the ship bobbing and rolling, you'd want even more down angle to not skip reliably. One other issue with 15 degree offsets...They're tougher to get on target than straight aft traditional sterns. As maneuverable as a QE is, if you put straight aft sterns on it aimed about 12" off the stern, you'll be plenty deadly and easily on target.
I will be putting the dual afts in Y. Aft cannons should be as low as possible with a flat trajectory. hitting 12-15". Skipping is appropriate with aft guns. My aft side mount (haymaker) will be in X. It will have a lot of down angle. Pull up along side, push against the side and pound belows . Bow side-mount will be in A 6-7" range. Trying to stay out of the range of the opponents Haymaker.
I suppose that a lot would depend upon what you spend most of your time battling. I want my Haymaker to have a lot of down angle to get belows. I want my aft guns to have a little more “effective” range. With the BB’s hitting the water at 12-15” I am doing damage anywhere from 6” to 24”. I do not expect my aft guns to get belows. We battle a lot of flag no flag, with (3) North Carolina’s in the club there is a lot of tasty bow to chew on. If I was always in a knife fight with a Baden (low freeboard cheating #%&@!!!) I might close up the range.
With my Baden (more or less equiv to QE: Same gun layout, slower but slightly better turning) I found I was emptying my sterns before even trying to engage w/ sidemounts. Sterns are just that much easier to aim.
The Tyng Barham is off the shelf and back under construction. Plan to have this ready for the fall regional. First thing to address is the pump location. I made a rookie mistake and placed it under the C turret where it was interfering with cannon placement. It gets moved forward a bit. The old location will get filled in.
Pump is moved and the old sump filled in. Lucky coincidence that my homes exterior trim color is an exact match for the TyngTech standard bilge color! I was planning on making turrets from scratch but when visiting the Grey Wolf Squadrons' Statesboro's production facilities, I couldn't pass these beauties up. The shortest run for the pump discharge is straight up. The superstructure that goes here will have a hole in it for the water flow.
I admit to being no expert. To me the 90 deg turn out of the pump would have more effect on the flow than a slightly longer hose coming straight out of the pump and running more to the side. I see a bunch of the pumps with that 90 deg turn. What am I missing?
You are missing: "The Bubble" When a pump primes the first thing it has to do is expell the last bit of water left. That last bit has a bubble attached, and the surface tension in that bubble will ruin your day unless you expell it fast. Hence the 90 deg. ell coming directly out of the pump. When ever I examine a pump failure this is the first item I look for.
